Abstract :
Sensorless control of the switched-reluctance (SR) stepping motor using pulsewidth modulation was introduced in an earlier paper by the authors. This scheme senses the dc link current and permits the motor to operate efficiently with a narrow pulsewidth under normal conditions. Changes in load are sensed by the dc link current, and the pulsewidth is adjusted appropriately. This paper describes the electric implementation of the controller.
